direction and push it slowly by hand so that
another seal (6) may be spread out evenly.
a The seal may be also fitted by pushing it
down to the flat surface of the tool and
then pushing it in with the tool fitted to the
piston.
5. Keep compensation tool T4 fitted to piston (2)
for about one minutes so that seal (5) and (6)
are adapted well.
a Check that there is no protrusion or cut on
the seal.
6. Assemble the piston in the sleeve.
a If it is found difficult to install the piston, do
not attempt to push it in forcibly, but set it
to compensation tool T4 again and install
the piston to the sleeve after adapting the
seal.
7. Fit plug (3) and spring (4) to piston (2), then
assemble pressure compensation valve (1).
a After the installation, push the piston by
hand and check that the piston reacts only
with spring force.
